When the Lenovo computer is turned on, there is a long and two short and three short sounds, and it

Dear Lenovo users, hello!

It should be a memory error, it is recommended that you re-insert the memory, clean the memory slot, if it is invalid, it is recommended that you contact the Lenovo service center for testing, the specific address and contact of the service center**Please refer to the following link: (It is recommended that you contact the service center before going).

One long and two short is the failure caused by the problem of the graphics card, what model of this? 80% of them are faults caused by overheating of the graphics card. There are also some graphics cards that are defective and aging and need to be replaced with a new and improved graphics card.

There may be several reasons for this:

1. The environment where the computer is located is humid, the dust is large, there is a lot of dust in the chassis, and there are too many oxides on the gold finger of the memory module, resulting in poor contact and unable to pass the self-test;

2. The computer is in poor contact due to loose memory modules caused by moving vibration;

3. The memory module is broken.

Solution: In the first two cases, you can open the chassis to remove the memory module, clean up the dust and oxide on the gold finger, and then plug the memory module back in, which can solve the problem;

In the third case, you can change the memory module to a slot and then start it up, if the limb luck is still a long beep alarm, you can confirm that the memory module is damaged, you need to replace the new memory module of the calendar beam.

In both cases, either there is a problem with the memory, open the chassis and pull out the memory, and reinsert it; Either it's a keyboard issue, reconnect the keyboard to the chassis and check if the keyboard has any keys.

The memory is not well connected, take it off and wipe it with a skin eraser, and you can install it.

This should be the memory module is not plugged in properly.

When the computer is turned on, we hear a variety of different "beeps" from the small speaker of the case, which is actually the computer sending us a message. The meaning of the "beep" sound is different for different kinds of BIOS. The meaning of the POST prompt for two common BIOS prompts is listed below for your reference.

ami bios

1 short beep: Memory refresh failed.

2 short beeps: Memory ECC verification error.

3 short beeps: The self-test of the system basic memory (the first 64KB capacity) fails.

4 short beeps: The system clock is wrong.

5 short beeps: CPU error.

6 short beeps: Keyboard controller error.

7 short beeps: The real mode of the system is wrong and cannot enter the protection mode.

8 short beeps: Displays a memory error (e.g. displays memory corruption).

9 short beeps: Motherboard FlashROM or EPROM verification error (e.g. BIOS corrupted by CIH virus).

1 long and 3 short beeps: memory error (e.g. memory chip corruption).

1. Long and 8 short beeps: The display system is tested incorrectly (such as poor contact of the display data cable or graphics card).

award bios

1 short beep: The system starts normally.

2 short beeps: General error. You should go to CMOSTathe and reset the incorrect options.

1 long beep 1 short beep: There is an error in the memory or motherboard.

1 long beep 2 short beep: Wrong monitor or graphics card.

1 long beep and 3 short beeps: The keyboard controller is wrong.

1 long beep 9 short beeps: motherboard flashram or EPROM error (e.g. BIOS corrupted by CIH).

Non-stop long beep: The memory is not plugged in properly or the chip is damaged.

Non-stop ringing: The display is not connected to the graphics card.

Repeating a short "beep": The power supply is faulty.

No beep sound and no display: The motherboard power supply is not connected, or the power supply is damaged.

Judging from your situation, it is probably a memory problem, and it is recommended to check if the memory is plugged in tightly or damaged.

Summary. There are several causes of fever:1

If the heat dissipation port is blocked, you need to open the back case of the notebook, get the blocked heat dissipation port through, and use a cotton swab leather to remove the dust on the fan. 2.It is also possible that the laptop has been in contact with the desktop for too long, if it is not an office, you can buy a desktop cooling fan, remove the fan, and put the heat sink on the laptop where the heat is very hot, which can also help heat dissipation.

3.Sometimes the computer running the program configuration is too high, which will also cause the laptop to heat up, you can press the Ctrl Alt del key to enter the Windows Task Manager, and check if there are any programs that are consuming computer resources. If my answer is helpful to you, please also ask for a five-star good flat "Evaluate in the lower left corner" Looking forward to your like, your efforts are very important to me, and your support is also my further motivation.

Finally, I wish you good health and a good mood!

Lenovo computers keep making rattling sounds.

Friends, I really don't understand, you can be more specific.

Memory error, memory corruption.

When the computer is turned on, there is an alarm sound, which is generally caused by a problem with the computer's hardware. Such as graphics card, memory, etc. Different alarm sounds have different meanings, and the alarm sound is to give us a hint to tell us that the hardware problem of the computer comes from.

This allows us to diagnose and troubleshoot.

1 Short: The system starts normally. This is something we hear every day and it also shows that there is nothing wrong with the machine.

2 Short: General error, please go to CMOS setup and reset the incorrect option. 1 long and 1 short:

There was an error with the RAM or motherboard. Try to change the memory, if it still doesn't work, you have to change the motherboard. 1 long and 2 short:

Wrong monitor or display card. 1 Long 3 Short: Keyboard controller error.

Check the motherboard. 1 Long 9 Short: Motherboard flash RAM or EPROM error, BIOS corruption.

Try a different block of flash ram. Constant ringing (long sound): The memory module is not plugged in tightly or damaged.

If it still doesn't work, you can only replace a memory module. Ringing: The power supply and monitor are not properly connected to the graphics card.

Check all the plugs. Repeated short rings: Power supply issues.

No sound, no display: Power issue.

Check that the monitor cable is firmly and reliably plugged into the host interface, and then check that the contact between the graphics card and the motherboard's I-O slot is good; If the computer starts normally with another monitor, the original monitor may be damaged; Check if the CPU fan is running; You can remove all components except the CPU, graphics card, and memory sticks, and then power on the computer. If there is a fault in the memory, there should be an alarm sound. If there is no alarm sound, then turn on the CPU and re-detect.

If the computer screen is still black, it is recommended to replace the motherboard; Whether the system has installed software and update patches, and if so, uninstall the update files; After installing the software on the computer, restarting the update results in a black screen, just wait for the update to complete; You can go into safe mode to repair your computer, if you can't enter safe mode, please reinstall the system.

If it is a notebook, it is recommended to send it to the designated maintenance point during the warranty period, if the warranty period has passed, you can first disassemble the back cover of the machine by yourself to confirm the working status of the fan, of course, it is best to send it for professional maintenance to avoid damage to the machine when disassembling the machine. 2 Short: General error, please go to CMOS setup and reset the incorrect option.

It is that the actual speed of your CPU fan is less than the CPU fan speed set by BIOS.

press

f2tocontinue,del

toenter

Setup translates into Chinese as: press the F2 key to continue, press the del key to enter the settings interface. (Some motherboards may prompt you to press the F1 key to continue).

In most cases, it is caused by the CMOS battery being de-charged and the settings being restored, if so, then the only way to change the battery is to change it, otherwise there will be a problem even if it is set up and started next time. There is also an incorrect hardware connection, usually the keyboard or something is not connected. It is also caused by incorrect settings.

There is a coin cell battery on the motherboard to keep the computer running the BIOS settings and continue to run the motherboard clock when the power is not on, and this can also happen if the coin cell battery runs out of power. At this time, you first need to disconnect the power cord of the computer host and turn on the computer case.

Locate the coin cell battery on the motherboard.

Use a flathead screwdriver to pry the battery off.

Reinstall a new CR2032 battery.

Turn off the case, connect the power cable, and start the computer. Press the DEL key to enter the BIOS settings and restore the default settings of the computer.

Save the settings and exit the BIOS to restart the computer.

You need to press the F2 key to enter the boot, mainly because the settings in the BIOS do not match the real hardware data, which can be divided into the following situations:

If the computer does not have a floppy drive installed or the floppy drive fails, but there is a floppy drive in the BIOS, this situation will cause an F2 prompt.

In most cases, you only need to restore the default settings of the BIOS to get back to normal.

Some older motherboards will also enable floppy drives by default, so please select the first item "Standard" after entering the BIOS

cmosfeatures”。

Once entered, it will "drive."

Go back to the main BIOS settings screen and select "Advanced."

biosfeatures" and press the Enter key to enter.

Add "boot

Press F10 to save, exit the BIOS settings with the ESC key, and restart the computer.

Check whether the battery is about 3V (replace the battery if the voltage is insufficient);

Press F1 to enter the BIOS, press F9 to restore the default value, then reset the BIOS, press F10 to save and exit after setting.
